Abstract: Besed upon the field survey running three times in 1972-1974, the authors have analysed stanting with the natural conditions and studied emphatically the floristic composition and characteristics of vegetationtypes, the main types of vegetations and the rule of their distribution over that region. In this paper the authors suggest some ideas and proposals in respect to the economic eva-luation and available utilization of the vegitational resources in that region All the vegetation data may provide certai scientific basis for reasonable exploitation of the regional vegetational resources.
